To all 'wkom it may concern: 7

Be it known that l', Gnocch D. Rooms,

a citizen of the United States, residing at Cleveland, in the county of Cuyahogaand State -of Ohio, have invented certain new useful Improvements in High-Tension harg'e Appa'ratus,of which the follow-4 1 is a specification.

' compact ,in arrangement, inexpensive to manufacture, and is adapted to be connected to an ordinary electric lamp socket.

In order that the invention may be clearly understood, reference will be had to the'ac- ,companying drawing which diagrammatiin the ordinary manner.

cally illustrates the same, and the novel features thereof will be distinctly pointed out in the appended claims.

Referring to the drawing, 1 and 2 represent conductors extendingfrom a plug 3 which is adapted to be connected to an ordi nary electric lamp socket. The conductor; 1 leads to an energizing coil 4 of exceeding high resistance passing around the iron core 5 of an electro-magnet, which is adapted to attract the armature 6 carried by a spring 7, connected with the conductor 2, for automatically .making and breaking the circuit The end 8 of the energizing coil 4, y means of a wire 9, is connected to the usual adjustable contact, indicated at, 0, which is adapted to normally engage the armature 6 as shown.

Leading from the end 8 of the energizing coil 4 is a wire 11, which extends to the is connected to the conductor 2 by neans of a. wire designated by 16.

Application for ree'rably consists of a few turns of heavy wire, and to its end 13 is connected the secondary winding 1'? comprising many turns of com-- high frequency coil is connected'to a'therapeutical instrument or other similar appliance requiring high tension. charges for effective operation.- By having but asingle terminal as 18 leading from the secondary winding of the high frequency coil for connection to an instrument, it has been found in practice that the eiliciency of the instrument has been greatly increased.

When the plug 3 is connected toan ordinary electric lamp wall socket, current of about 110 volts is drawn through the conductor 1, passes around the iron core 5 through the energizing coil thence from its end 8 through the wire 9, and by the contact 10 to the armature 6, which as shown is normally in spaced relation to theend of the iron core 5. The current then passes through the spring 7 to the conductor 2, thus completing the main circuit. The iron core 5 upon being magnetized attracts the armature 6, thereby breaking the main circuit between 6 and 10. The instant the main circuit is broken, the sudden interruption of the flow of the supply current due to the breaking of the circuit, causes said current to charge the condenser 15 by passing through the wire 16, and then cease while the main circuit is broken between the armature 6 and the contact 10. instantly, the

condenser begins discharging through .the

wire 16 and conductor 2, through the spring 7, then across the are between the armature 6 and the adjustable contact 10, by way'of the wires 9 and 11 to energize the primary winding 12 of the high frequency coil, then back through the wires 13 and 1 1 to the condenser, which elements constitute the condenser discharging circuit. The moment the armature 6 .is drawn to the iron core 5 and while the main circuit is still broken between the armature 6 and the adjustable contact 10, the iron core 5 becomes nonmagnetic and the spring 7 returns the armature toits normal position in engagement with said contact.

As will be understood, the rapid auto matic operation of the armature 6 will make and break the circuits as described, the condenser will thereby become charged and then discharge with great frequency, thus inducing currents of high tension into the 1 primary Winding 12 of the high frequency coil, and this high frequency tension is further increased by inducing said current into the line secondary winding 17. A suitable instrument connected to the free end or terminal 18 of the secondary Winding 17 Would therefore receive current of very high frequency and intensity from an initial current of comparatively low voltage. 1 e

Itwill beunderstood that the invention as set forth and described is not limited to this particular arrangement of the details of construction and circuits but that the same may be modified as required in practice without departingfromlthe spirit of v coil' having one end connected to the prie' mary Windmg thereof and terminating in a theinvention, v y Havingdescrlbed lily-invention, What I claim is i 1.
